Should a surgeon fix my breasts for free if one is the wrong size?

I had my breasts done in December 2015, and I have been aware that the right breast is slightly droopier and less full than the left, and is slightly doubled over at the crease. I had the procedure done in Phuket, so I avoided taking action against it. They are high profile, 325 cc R 350cc left. I am thinking that I need a bigger implant in the right, or the implant has come out of its pocket. When I lay down I can see a dark hollow line on the right. What is the surgeons obligation in this?
